Security updates Windows no longer require frequent reboots

Since early May 2026, a U.S. company has introduced Hotpatching technology for compatible devices, allowing security updates to be applied without a full system reboot. This technology replaces code fragments directly in the RAM of running processes, reducing the size of downloaded packages and enabling quicker implementation of critical patches. The update mechanism operates on a hybrid schedule with four base months requiring mandatory reboots for cumulative changes and eight hotpatching months focusing on in-memory security fixes. If extensive architectural changes are needed or if the software environment does not meet standards, the system defaults to a standard installation algorithm that requires a reboot. The technology is designed for corporate infrastructures with high operational demands and requires Windows 11 version 24H2 or later, specific editions, and enabled VBS virtualization protection.

Microsoft enables Hotpatching by default: Windows updates without restarts become a reality

Beginning in May 2026, Microsoft will introduce Hotpatching as a default feature for compatible systems, allowing security updates to be applied without requiring a restart. Hotpatching updates code directly in the memory of running processes, enabling selective updates without interrupting the entire system. It does not replace monthly security updates but alters their activation process on eligible systems, categorized as security updates within the monthly B releases. Eligible systems must be running Windows 11 version 24H2 or newer and possess suitable licenses such as Enterprise, Education, Microsoft 365, or Windows 365. Management of these updates will be facilitated through Windows Autopatch or Microsoft Intune. Microsoft will continue to utilize baseline updates that require a restart, which will alternate with Hotpatch months. Hotpatching aims to reduce the frequency of restarts tied to security updates, particularly benefiting environments where uptime is critical. However, planned restarts will still be necessary, and robust telemetry and maintenance practices will be needed to ensure smooth operation.

Hotpatching goes default in Windows Autopatch whether you like it or not

Microsoft will enable hotpatch security updates by default starting with the May 2026 Windows security update. Hotpatch updates allow security enhancements to be applied without system restarts, while quarterly baseline updates will still require a restart. Windows Autopatch will manage updates using "testing rings" to progressively roll out updates and address any issues. Devices must run Windows 11 24H2 or later and have the April 2026 security update installed to receive hotpatch updates automatically. Existing update policies will remain intact, and administrators can opt out of hotpatch updates at the tenant or group policy level.

Microsoft WSUS Patch Breaks Hotpatching on Windows Server 2025

A recent Microsoft security update (KB5070881) aimed at fixing a critical vulnerability in the Windows Server Update Service (WSUS) inadvertently disrupted hotpatching for some Windows Server 2025 systems enrolled in the Hotpatch program. This disruption prevents affected servers from applying updates without requiring a restart, forcing administrators to revert to traditional cumulative updates until January 2026. The vulnerability, CVE-2025-59287, allowed potential remote code execution by exploiting weaknesses in WSUS. Microsoft has since released a new update (KB5070893) that addresses the vulnerability while restoring hotpatching capabilities for those who have not yet installed the problematic update.

Microsoft: Patch for WSUS flaw disabled Windows Server hotpatching

An out-of-band security update, KB5070881, has disrupted the hotpatching feature for some Windows Server 2025 devices. This update was released alongside reports of the CVE-2025-59287 remote code execution vulnerability. The Cybersecurity and Infrastructure Security Agency (CISA) has instructed U.S. government agencies to strengthen their systems against this vulnerability. Microsoft has acknowledged that the OOB update caused some Hotpatch-enrolled Windows Server 2025 systems to lose their enrollment status and has ceased distributing the update to these devices. Those who installed the update will not receive Hotpatch updates in November and December but will get standard monthly security updates. Administrators can install the KB5070893 security update to address the CVE-2025-59287 flaw without disrupting hotpatching. Microsoft has also disabled the display of synchronization error details in its WSUS error reporting system and resolved various issues affecting Windows 11.

Microsoft: New policy removes pre-installed Microsoft Store apps

Microsoft has introduced a new app management policy for IT administrators managing Windows 11 Enterprise and Education devices, allowing the removal of pre-installed Microsoft Store apps (in-box apps). This feature is available for devices running Windows 11 Enterprise 25H2 and Windows 11 Education 25H2 through management tools like CSP, GPO, and Microsoft Intune. The policy simplifies app management by eliminating the need for custom installation images and complex scripting, enabling administrators to efficiently select and remove apps from a predefined list. The policy is disabled by default and must be enabled by administrators. It is compatible with both Group Policy and MDM solutions, including Microsoft Intune. Implementation steps for Microsoft Intune include creating a new policy in the admin center, configuring settings to enable the removal of default Microsoft Store packages, and assigning the policy to desired device groups.

Transforming security and compliance at Microsoft with Windows Hotpatch

Security updates are crucial for system integrity, but traditionally require a reboot, causing productivity interruptions. Microsoft has introduced Windows Hotpatch, which allows critical updates to be applied without rebooting, enhancing compliance and user satisfaction. Hotpatch modifies in-memory code while the system is operational, leading to immediate updates without downtime. It is designed for efficiency with small payloads that minimize performance impact. Hotpatch updates undergo the same validation as standard updates and can address zero-day vulnerabilities without requiring a reboot. This technology is available for Windows 11 version 24H2 or later, Windows 365, Azure Virtual Desktop, and Windows Server 2022/2025 Azure Edition, with appropriate licensing. Hotpatch has evolved from internal server capabilities to support client machines and integrates with Autopatch, automating the update process for enterprise environments. Microsoft Digital plans to scale Hotpatch to 450,000 devices within four months, achieving high compliance rates quickly—81% within 24 hours and 90% within five days, compared to previous timelines of up to nine months. Since its general availability in April, Hotpatch has been deployed to over 4 million devices globally, enhancing user experience by making updates seamless and unobtrusive. Plans for further expansion and improvements in compliance visibility and reporting are underway.
